Efficiency

The Voodoo Doctor is an above average statistic minion at 2/1 for 1 mana. He becomes immediately mana efficient when there is another Minion that needs a heal on the board.

It is not recommended to use him early game just to heal your Hero as he is considered a minion that is used for board control, it is in a players best interest to use him to heal on of your other minions to give them more effciency and value.

Uses and Tactics

The Voodoo Doctor can cast a heal on any target for 2 health when summoned. This can be useful to keep your Hero's HP up or to patch up a damaged friendly minion.

If the target is at full HP then there is no effect.

Can be used in conjunction with a Northshire Cleric in order to activate their abilities to draw cards.

Is very useful in a Warlock deck to make-up for the HP lost from his Hero Power.

A Priest can make good use of Voodoo Doctors by improving his already strong healing powers.

Trading hits with enemy minions then summoning this card is a good way to make sure you get the most out of it.
